"2008- In May and June, Google Chrome 2.0 and Opera Mobile 9.7 beta displayed a score of 100/100, but did not actually pass; release versions of these browsers passed fully later in the year. Security concerns over downloadable fonts delayed Chrome from passing."

Opera 10 is a version of the Opera web browser. The initial version, 10.00, was released in September 2009.
In comparison to 9.x versions, Opera 10.50 uses Presto 2.5.22 which improves rendering speed, adds support for web standards such as RGBA/HSLA color, border-radius, and CSS transitions, and improves existing support for web standards. From 10.00, Opera passes the Acid3 test.
